Purpose and Specifications

LIQUI MOLY 4427 GL3+ 75W-80 1L is a fully synthetic high-performance gear oil designed for manual transmissions and gearboxes in trucks and passenger cars. It delivers smooth shifting by providing the right friction for synchronizers across a wide temperature range, from cold starts in freezing conditions to hot highway driving. This premium oil offers outstanding corrosion protection, excellent wear resistance, and high pressure absorption to keep gears running quietly and reliably for longer.

Approved for major brands including DAF, IVECO, MAN, Renault Trucks, Volvo, and ZF transmissions, it supports extended drain intervals up to 300,000 km in Eaton systems. The 75W-80 viscosity flows easily at low temperatures down to -40°C for quick protection on startup and stays thick at high temps up to 150°C.

When to Use / Replace?

Use this oil in manual gearboxes requiring API GL3+ specs, especially if you notice stiff shifting, gear noise, or grinding. Ideal for heavy-duty trucks and cars with Getrag or similar transmissions. Replace every 100,000-300,000 km or 3-5 years based on manufacturer guidelines and driving conditions; check fluid level monthly. Shelf life is 5 years unopened when stored cool and dry.

• Perfect for winter driving - pumps fast in cold weather
• Handles towing and heavy loads without breakdown
• Mixes with old mineral oil for easy changes
